Action-film star Jean-Claude Van Damme might have accomplished something more amazing than any stunt in his movies: a Volvo truck commercial that shows “the Muscles From Brussels” doing one of his famed splits between two tractor-trailers moving backward and farther apart.

The ad, titled “The Epic Split,” went up Wednesday on YouTube and has been viewed more than 7 million times. It begins with a close-up of his face.

“I’ve had my ups and downs,” Van Damme says, “my fair share of bumpy roads and heavy winds. That’s what made me what I am today. Now, I stand here before you. What you see is a body crafted to perfection.”

As the camera pulls back, the 53-year-old actor is seen standing on the rearview mirrors of the side-by-side trucks creeping along an airport runway in Spain. He has “a pair of legs engineered to defy the laws of physics,” he says, “and a mindset to master the most epic of splits.”

The two trucks are then shown moving apart, his legs spreading with them, until he reaches a full split across a 6- or 7-foot gap.

The stunt — designed to demonstrate a new, electronically assisted steering system — represents the real deal, Volvo says on its website. Some safety equipment standing by was digitally removed, but no other computer trickery was involved.

“The stunt is real and shot in one take without any breaks,” a publicist said yesterday on Today, later denying that it was shot in reverse, as some people theorized.
